IMPROVEMENT IN COMBINATION TOOLS.

Specification forming part of Letters Patent No. 132,90, dated November12, 1872.

To all whom it may concern: y

Be it known that I, DAVID HEATON, of the city and county of Providenceand State of Rhode Island, have invented a new and useful Improvement inthe Combination Tool known as The Household Implement,77 and patented byThomas Garrick May 9, 1871, of which the following is a specification,referring to the accompanying drawing making part of the same, in which-Figure lis a front view of the improved construction of said implement;Fig. 2 is a side view of the same and Fig. 3 is a view of the reverseside. Y

Similar letters mark like parts in all the figures.

My improvement consists in constructing the said implement, as hereinshown and described, with a sliding clasp for coniining and holding themovable jaw of the adjustable wrenchiirmly in position parallel with thelixed jaw while in use.

The said implement is in two parts, A and B, which are separable for theuse of either by itself, or co-operatively with the other, as for thepurpose of a screw-driver, S, in the first instance, or as a hammer, H,and carpet-stretcher J, or box-opener B, in the second instance. "When,however, the two part-s are connected together a very convenientadjustable wrench is formed by the sliding of the movable jaw D towardor from the fixed jaw F on the part A. .This is accomplished by theengagement of one or more teeth ofthe movable par-t with the set ofequidistant teeth f on the iixed part A,

and in order to make the said wrench more effectual anduseful I make theteeth with one perpendicular side and one inclined side as betteradapted to resist the strain, and for the purpose of the better dividingthe space into equidistant openings for the jaws to receive thedifferent standard sizes of nuts; and I further provide a slidingadjustable clasp, C, which slides upon the inclined surfacei ofthemovable jaw and on the straight under surface g of the fixed-jaw part A,and by so doing firmly embraces and holds the two parts A and Btogether, and both prevents Vthe jaws from slipping and gives additionalstrength to the parts without requiring the forcible gripe of the handupon both handles, as in the former construction without said clasp.

Vhen not in use the clasp rests, in the position shown in Fig. 2,against the projection k, Fig. 3, when the part B may slide freely onthe part A, or the two parts be separated; but when the jaw D is set inthe required position to fit upon the nut, by simply sliding the claspfirmly into the position shown by dotted lines in Fig. 3 the jaw D isheld rigidly in place, as :much so as if the two jaws were solidlyunited together. l

I claim- In the construction of the implement, as shown, a slidingadjustable clasp, O, as and for the purpose specified.

DAVID HEATON.
